QCD corrections to charged current processes at the Next Linear Collider: CC10, CC11 and CC20 at O(alpha_s)

Abstract

One-loop QCD corrections to the full gauge invariant set of electroweak diagrams describing the charged current processes $e^{+}{e}^{-}\to u\bar{d}\hat{I}¼\bar{\hat{I}}{½}_{\hat{I}}¼$ (CC10), $e^{+}{e}^{-}\to u\bar{d}{e}^{-}\bar{\hat{I}}{½}_e$ (CC20) and $e^{+}{e}^{-}\to u\bar{d}s\bar{c}$ (CC11) are computed. We compare the exact calculation with a ``naive''approach to strong radiative corrections which has been widely used in the literature and discuss the phenomenological relevance of QCD corrections for NLC physics.
